Working hard on a white paper that describes how best to go about evaluating the carbon content of the power delivered to you by your utility.
It's not as easy as it sounds, though there are a couple of places you can go to get a reasonable picture. I'll point out the limitations of California's mandated Power Content Label, why the federal government information resources are only good as far as they go, and why data centers in particular may overreport their carbon emissions if they use the average carbon content figures from their utility.
And if this wasn't difficult enough, I'm going to take a stab at a methodology for accurately predicting power rates - again, the average rate figures provided by utilities are poor predictors of costs for high load factor customers like data centers. No promises on when this one will be done, as I expect the case study comparing California utility rates will require a pretty detailed spread sheet analysis.
